Title: Cleaner head for a vacuum cleaner
Inventor: JONATHAN JAMES GRAY
IPC: A47L9/06
Filed: 2016-02-12
Abstract: A cleaner head for a vacuum cleaner comprises a suction inlet 20, a front blade 12 and a rear blade 13. The front blade 12 is located forward of or at the front of the suction inlet 20 and is arranged to pivot about a first axis. The rear blade 13 is located rearward of or at the rear of the suction inlet 20 and is arranged to pivot about a second axis different to the first axis. Each blade 12, 13 pivots between a deployed position and a retracted position, and projects downwardly when in the deployed position. Moving the cleaner head over a cleaning surface in a forward direction causes the front blade 12 to move to the deployed position and the rear blade 13 to move to the retracted position, and moving the cleaner head over the cleaning surface in a rearward direction causes the rear blade 13 to move to the deployed position and the front blade 12 to move to the retracted position.

Title: Predicting patch displacement maps using a neural network
Inventor: ZHE LIN
IPC: G06T5/00
Filed: 2018-08-15
Abstract: Predicting patch displacement maps using a neural network is described. Initially, a digital image on which an image editing operation is to be performed is provided as input to a patch matcher having an offset prediction neural network. From this image and based on the image editing operation for which this network is trained, the offset prediction neural network generates an offset prediction formed as a displacement map, which has offset vectors that represent a displacement of pixels of the digital image to different locations for performing the image editing operation. Pixel values of the digital image are copied to the image pixels affected by the operation by determining the vectors pixels that correspond to the image pixels affected by the image editing operation and mapping the pixel values of the image pixelsrepresented by the determined offset vectors to the affected pixels. According to this mapping, the pixel values of the affected pixels are set, effective to perform the image editing operation.
